ABSTRACT:
The electrolytic display cell comprises a plurality of electrodes having suitable shapes for character display, a counter-electrode and an electrolyte. A negative voltage is applied to one of the electrodes for writing on said electrode and a positive voltage is applied for erasure. On completion of erasure, the voltage between electrode and counter-electrode has a tendency to rise to a threshold value corresponding to a parasitic reaction. The end of the erasure pulses is determined by the instant at which the electrode--counter-electrode voltage rises to the threshold voltage corresponding to the production of a parasitic reaction.
